Fun Facts about the Blood Star

  • The only threats to these sea stars are by birds and by anthropogenic causes. Many beach tourists take the stars home not understanding that the star’s vivid color fades when it dies.
  • They can regenerate a lost arm if a portion of the central disk remains. They possess this ability even though sea stars have no brain and lack of any blood.
